Hollow chamber resonators
High attenuation in problematic, low-frequency ranges
Hollow chamber resonator pipe silencers are fully welded stainless-steel assemblies that provide high attenuation with virtually no pressure drop, as these systems operate without additional inserts in the exhaust gas stream.
Industrial silencers, which are particularly effective at low frequencies, are characterized by the following features:
- Material selection depending on the operating temperature
- No cores or splitters, thus there is hardly any measurable pressure loss and no additional operating costs
- Largely wear-free metal system (without mineral wool)
- Noise attenuation over a wide frequency range is possible through various chamber combinations
Cooperation with Fraunhofer Institute
The exhaust silencers were developed in cooperation with the Fraunhofer Institute for Building Physics in Stuttgart. In both the standard silencers and the special solutions, the resonator chambers are matched to the corresponding engine frequencies, among other things. The higher orders can also be damped using appropriate chamber combinations.
